Overview

Till date, all display panels used to refresh the entire screen of KPIs at fixed intervals, regardless of whether every data point truly needed frequent updating. This resulted in unnecessary system load, a high volume of queries to reporting engines, and increased overhead in managing publishing workflows.

We have introduced a per-widget Rapid Refresh feature, allowing selective, high-frequency refreshes directly from the browser - similar to how drilldown queries currently work.

Feature Details

1. Per-widget rapid refresh: Enable selective widgets to fetch data at short intervals directly from the browser.

2. Hybrid refresh model: Mix of rapid and standard refresh intervals on the same display.

3. Optimized performance: API proxy caching and widget-level query control reduce backend strain.

4. Governance controls: Limits on widget count, time range, and supported engines.

5. Improved visibility: Freshness indicator shows last query time alongside publish timestamp.

How to Enable Rapid Refresh Feature for a Widget

1. Go to a widget in your Display platform/site.

2. Click on Data on the right panel.

3. Check the Rapid Refresh option under Advanced. The rapid refresh option will be enabled for the selected widget.
